ABSTRACT
This descriptive, cross-sectional study was based on subjective questionnaires that assessed nighttime habits of television viewing and Internet use during weekdays and perceived sleep quality among university students. Sleep perception was measured using the Pittsburgh Sleep Quality Index (PSQI). The study group comprised 710 university students aged 17-25 years. Analysis of sleep perception in relation to internet use revealed that 58.06 percent of subjects who accessed the internet between 19:00 and 21:00 slept poorly; 71.43 percent between 19:00 and 22:00; 73.33 percent between 19:00 and 24:00; and 52.38 percent between 19:00 and 03:00 (p=0.0251). Concerning the relationship between television exposure and perceived sleep, the groups did not differ from each other (p=0.9303). This study showed that internet use between 19:00 and 24:00 increases the risk of poor sleep among young adults, in comparison with television viewing times.
RESUMO
Este estudo transversal descritivo com base em questionários subjetivos avalia o hábito de assistir TV e acessar a internet durante as noites nos dias de semana e a percepção da qualidade do sono entre universitários. Para avaliar a percepção do sono foi aplicado o Índice de Qualidade do Sono de Pittsburgh. O grupo estudado incluiu 710 universitários entre 17-25 anos. Para as análises da percepção do sono relacionado ao hábito de acessar o computador observou-se que acessam a internet e dormem mal: 58,06 por cento entre as 19 e as 21h; 71,43 por cento entre as 19 e as 22h; 73,33 por cento entre as 19 e as 24h; 52,38 por cento entre as 19 e as 3h (p=0,0251). Em relação aos horários de assistir TV e a percepção do sono os grupos não se diferenciaram entre si (p=0,9303). O estudo demonstra que acessar a internet durante os horários das 19 às 24h aumenta as chances dos jovens dormirem mal quando comparado aos horários de assistir TV.
